Here is a fairly new resource that follows the same concept of information democracy that Wikipedia
imploys, but with different options and in a Q&A format some may prefer (this one has a voting/grading mechanism so you can kind of gage the accuracy or level of certainty on a particular answer).
Here is the MA section:http://www.answerbag.com/c_view.php/440
The MA info is pretty fragmented and incomplete right now, but keep in mind, these grow over time.
For what it's worth.
p.s. It would be interesting if we had a voting mechanism for each other's posts (not just topics) on this forum...the best answers of everyone's post given a particular topic would bubble to the surface leaving a person doing research to find he best info quicker. just a thought for improvement.
